This invention relates to certain new'and useful improvements in a beam and mounting frame for Axminster looms.

The primary object of the invention is to improve the yarn spool or beam and the mounting frame therefor by constructing the beam in a manner whereby practically all yarn wound thereon may be utilized in the weaving operation and eliminating the loss of comparatively long ends of yarn that has heretofore been utilized in effecting the winding of the yarn on the beam.

It has heretofore been customary to employ spring devices engageable with end flanges on the beam to provide proper tension on the yarn when being unwound from the beam, but it has beenfound that it is-extremely diflicult to obtain proper tension with the result that if frictional contact between the spring devices and the beam flanges is excessive, the yarns will break andinterfere with the weaving operation and a further object of this invention is to associate a single spring device with one end of the beam and to provide a freely rotatable gear and pinion combination at the other end of the beam with a single spring providing proper tension and insuring even and steady unwinding movement of the beam.

A still further object of the invention is to improve the mounting for the spring catch that is engageable with a link of the carrier chain whereby the spring catch may be readily removed from the frame without disturbing the beam bearing and carrier chain engaging arm in the event of breakage of the spring catch or for other purposes.

With the above and other objects in view that will become apparent as the nature of the invention is better understood, the same consists in the novel form, combination and arrangement of parts hereinafter more fully described, shown in the accompanying drawings and claimed. 1 V

Referring more in detail to the accompanying drawings,there is illustrated a beam and mounting frame for use in Axminster ma;

yarn moved into the chines, the beam 15 in the form of a yarn L 9 7 spool being removably supported in a mount- 1ng frame 16 that carries end bearings for 7 the beam with the carrier chains 18 of an Axminster machine being detachably engageable with parts of the bearings.

The beam comprises a tubular metal cylinder 19 that is longitudinally slotted'as at terminating laterally of the slot 20 in the tuwheel 25,

bular cylinder 19. The wall of the tubular cylinder 19 at each end thereof is enlarged inwardly as at 23 and internally threaded for the reception in one end of a friction flange disk24 while the other end receives a gear wheel 25. The friction disk 24 and gear each carry an axial offset tubular bearing 26 both internally and externally threadedfor threaded reception in the re spective ends of the tubular cylinder 19, the bearing pin'27 for each end of the beam carrying a screw stud28 threaded into the bearing 26. With a construction of this character, it is possibleto replace the friction disk 7 24 or gear wheel 25 as well-as the bearing'pins 27 should any of these parts become worn or damaged. V

The manner of securing the ends of the yarn strands to the beam 15 is illustrated in Figures 3 to 5, 8 and 9,'the yarn strands 29 being positioned over the longitudinal slot 20 in tance,

the beam 15 with the free ends of the yarn strands projecting only a slight disbeyond the beam as illustrated. The device for inserting the ends of the yarn strands into the interior of the tubular cylinder 19 of the beam is shown in Figure 4 as comprising a rod 30 of substantially the same length as the beam slot 20 with a hand grip 31 at each end thereof, the rod 30 is positioned with respect to the yarn ends and beam as illustrated in Figure 8 and is then moved downwardly through the slot 20 in the beam as illustrated in Figure 9, carrying therewith the yarn ends 29a which are substantially entirely confined within the tubular beam. The yarn pressure 30 is then removed from the tubular beam and the latter manipulated in an appropriate manner for the winding of the yarn strands 29 there'on. It is to be noted that the presence of relatively long waste ends of the yarn strands are eliminated resulting in a great saving of yarn material as a minimum lengh of the yarnend is required for'attaching the same to the beam. v V v The beam carrying the yarn wound thereon is then placed in the mounting frame carried by the Axminster machine, the mounting frame 16 including a bar 32 having opposite ends at the uppersides thereof rabbetted for the reception of the base portion 33 of a bearing bracketthat carries an upstanding leg rying a depending catch is provided with that is bifurcated at its upper end to provide side lugs 35 and 36 and an intermediate bearing for the adjacent bearing pin 27 of the beam 15. The base portion 33 of the beam bearing bracket is anchored to the bar 32 by a pair of spaced screws 37 and 38. The bearing pins 27 are retained in the bearings at the upper ends of the legs 34 of the angle bracket by means of a latch 39 pivotally mounted as at 40 upon the bracket legs 34, the

' latch plate 39 including a side edge leg 41 latat its upper end and carlug 43 that overlies the bearing between the spaced lugs 35 and 36 to be engaged with the associated bearing pin 27, thelug 36 being laterally offset as illustrated in Figure 6 to be engaged by the lug 43 upon the latch plate, to retain the latter in its closed position, the latch" plate being of a resilient character so that the upper=endthereof may be properly shifted to displace the cO-acting lugs 36 and 43 to permit pivotal movement of the latch plateupon the pin 40 for'assuming the dotted line position shown in Figure 12.

The lower face of each end of the bar 32 is mitered for the reception of the base portion 44 of an angle arm that has an end portion engaged with the leg 34 of the bracket bearing and is offset at its upper end as at 46 to receive a link of the carrier chain 18. The base portion of the angle arm is secured to the bar 32 by a pair of spaced screws 47 and 48.

The end portion of the angle arm is longitudinally slotted as at 49 for the passage of the leg of the spring catch 50 that has a lower angle end 51 disposed between the bar 32 and base portion 44 of the angle arm, the lower angle end 51 of thespring catch having an opening therein through which the screw 48 passes with the terminal end thereof bifurcated as at '52 to straddle the shank of the screw 47. The other end of the spring hook 53 to overlie a side of a chain link engaged with the offset portion 46 of the angle arm, the spring catch extending upwardly through the slot 49 in the angle arm as shown in detail in Figure 6. I To remove the spring catch for replacement or other purposes, it is only necessary to. remove the single screw 48 so that the remaining portion of the bearing for the beam is undisturbed.

In lieu of the usual double use of spring tensioning devices for opposite ends of the beam 15, a single spring device is employed and is associated with the friction disk 24, the spring device comprising a spring arm 54 anchored as at 55 to the upper side of the bar 32 and carrying a friction shoe 56 positioned to be engaged by the peripheral edge of the friction disk 24 as shown in Figure 6. It has been found that where two spring de vices are employed, one for each end of the erally offset as at 42 beam, that it is practically impossible to obtain like frictional engagement with each end of the beam so that. the tension on the yarn strands is varied, resulting in breakage thereof. v

The end of the beam 15 carrying the gear wheel has the gear wheel engageable with a pinion 57 supported by the adjacent leg portion 34 of the bracket bearing and a removable angle bracket 58 shown in detail in Figure 7 as having a base portion 59 mounted on the bar 32 beneath the base portion 33 of the adjacent angle plate. The base portion 59 of the angle bracket 58 is provided with an opening 60 through which the screw 37 passes-while the free end of the base portion 59 is slotted asat 61 to straddle the screw 38. To remove the pinion 57 it is only necessary to remove the screw 37 and slide the angle bracket 58 longitudinally of the bar 82 as will at once be apparent from an inspection of Figure 6; The gear and pinion-combination 25 and 57 promote even rotation of the beam 15 and relieve the yarn strands of undue pulls and strains during unwinding movement of the beam.

From the above detailed description of the invention, it is believed that the construc tion and operation thereof will at once be apparent, it being noted that the foregoing improvements in the beam and mounting frame are to be embodied in devices of a character to which they relate, only the novel features of theinvention being herein illustrated with the exception of the carrier chain 18 and the tubular eyes or quills 62 fragmentarily illustrated in several of the figures.

While there is herein shown and described the preferred embodiment of the invention, it is nevertheless to be understood that minor changes may be made therein without departing from the spirit and scope of the invention as claimed.
